Strait of Hormuz traffic returns to normal by September 30?

Platform comparison

Market context

Polymarket prices this at **22% YES**, with traders on Polygon posting **USDC** against conditional tokens that settle on whether IMF Portwatch’s 7-day average of Strait of Hormuz transit calls reaches **60 or more** before 30 September. In plain terms, the market is asking whether traffic can get back to something close to normal shipping volumes, not just whether the strait is formally open. The threshold matters: it is based on IMF Portwatch’s published “Arrivals of Ships” series, and ships not captured in that feed do not count.

The historical read-through is still bearish for a full reset. Reuters reported in April that Hormuz traffic was running at less than 10% of typical volumes even after ceasefire headlines, while other contemporaneous reporting described only a handful of vessels a day, far below the pre-war pace of roughly 100 daily transits.[2][3][4][6] More recent coverage in mid-July said hostilities had intensified again, with a U.S. strike on a supertanker near Kharg Island and shipping volumes still under pressure.[7] Against that backdrop, a 60-vessel 7-day average looks less like a modest improvement and more like a near-complete normalisation of lane usage.

Traders should watch for three things: any bilateral security announcement affecting naval escort or inspection rules, tanker chartering behaviour from major Gulf exporters, and whether Portwatch’s own seven-day average begins to trend steadily higher rather than bouncing on one-off sailings. CNN reported in June that an agreement was meant to let commercial navigation commence immediately and that vessels would be allowed to pass without tolls for 60 days, but the same reporting also noted that traffic remained far below pre-conflict norms.[5] For this market, the practical question is not diplomatic language, but whether enough container, bulk, ro-ro, general cargo and tanker movements are actually logged to keep the Portwatch average at or above the trigger level.
